The spindles are mounted in spherical bearings 77 constrained by a spring 79. Driving-arrangements; building-motions; stopmotions; rollers. - The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter. Spinning and twisting machines are driven from an electric motor 1 through a change-speed box 5, Fig. 1, (Cancelled), the driven shaft 21 of the change-gearing carrying the driving-pulley 36 of the spindle-driving band 37 and driving - through change and reverse gearing 41, 44 " feedcontrol shafts 46, 49 on each side of the machine, from which the building-motion cam 94, the - wipers of the stop-motion, and the delivery rollers are driven. The motor shaft is directly coupled to the prime shaft 4 of the change gearing, which is geared with one or another of a nest of gears on a secondary shaft 16, Fig. 3 (cancelled), by means of a pinion 9 movable along a shaft 8 by means of a fork 10, a rack 10<1>, and a pinion 12, the shaft 8 being adjustable relatively to the shaft 4 to permit the gearing with the different wheels of the nest by a pivotal mounting 7. Each end gear of the nest engages a gear loose on the shaft 21, and a clutch 24 operable by a lever 27 is arranged to couple one or the other of the loose gears to the shaft 21 or to be neutral. The wiper-shaft 63 Fig. 2 (cancelled), of the stop-motion is oscillated by a crank-disc 59 on a shaft 54 driven through a clutch 56, 57 and helicoidal gearing from the shaft 46. The delivery roller 64, Fig. 8 (cancelled), is driven by gears 65, 66 from the shaft 46, and a porcelain roller 72 is adjustably secured by a screw 69 in a relatively inclined position thereto so that the thread in passing therearound assumes a spaced relationship as regards the coils by reason of its tendency to ride to the highest part. The building-motion cam engages an irregular fivesided bowl carried by a lever fixed on a shaft 96, Fig. 11 (cancelled), which carries rocking arms 98 coupled to levers 101, 101<1> operating the pokers so as to constitute a self-balanced mechanism.

Patent GB-1030288-A (GB)
Title: Method of making a polymeric strap
IPC: B29C48/885
Filed: 1964-08-04
Abstract: 1,030,288. Films. FMC CORPORATION. Aug. 4, 1964 [Aug. 27, 1963], No. 30811/64. Heading B5B. A strap of hot polymeric material is oriented by imparting stretch to a straight line segment of the strap while positively preventing any stretch from being imparted to any other portion of the strap. Specified polymeric materials include polyethylene and polypropylene, polycarbonates, polyesters, polyamides, e.g. polyhexamethylene adipamide, acrylic resins and polystyrene. Stretch may be imparted to the strap between a relatively slow hot drum 32 or 42 and a relatively fast cold drum, 34 or 44, any stretch on the curved surface of the hot drum being prevented by nipping the strap against the hot drum at the point of departure of the strap therefrom, e.g. by rolls 33 or 43. As in Fig. 2, the strap may be directed tangentially of the cold drum and nipped against the drum at the point of tangency. One side of the strap is rapidly cooled by contact with drum 34 while the other side of the strap cools more slowly and shrinks to a narrower width than the rapidly cooling side, thus producing a cambered strap as in Fig. 4 (not shown), the convex side 15<SP>1</SP> being that which was in contact with the drum. Such straps have some coil set due to the passage of film about drum 23, but this can be substantially eliminated by winding the strap in the opposite direction on reel 27. Alternatively, both sides of the strap may be brought to the same temperature while in engagement with the fast drum, suitably, as in Fig. 3, by immersing the strap in a liquid medium while the stretch is being imparted thereto. Straps so made are free from camber owing to the absence of a temperature differential between the two sides of the strap, and are free from coil set as the drum 23 of Fig. 3 is at substantially the same temperature as the strap.

Abstract: 896,281. Aerials; radar. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Sept. 7, 1960 [Sept. 22, 1959], No. 30895/60. Class 40(7). A system for providing a volumetric display of objects present in the surrounding space comprises pulse radar apparatus 5 coupled to an aerial 1 cyclically scanning in a plane containing the aerial and mounted for rotation about an axis 10 in the plane. The display comprises an electro-luminescent screen 7 scanned in synchronizm with the aerial scan in the said plane and rotated about an axis 11 in its plane in synchronizm with the aerial rotation. The output of the radar receiver is applied to the electro-luminescent display and if the rotation speed is sixteen revolutions per second or higher a three dimensional display is obtained owing to persistence of visual sensations. The scanning in the plane, which is the elevation scan as shown and may cover 30 degrees, is effected electrically at a much higher speed than the speed of rotation by an aerial arrangement which may comprise an array of parallel microstrip lines having radiating discontinuities. The feed to these is through a waveguide containing a ferrite rod surrounded by a coil 3. A sawtooth waveform from generator 4 is applied to the coil and varies the plane velocity of energy propagated along the waveguide to produce the scan. An aircraft may be equipped with two systems having aerials mounted respectively above and below the fuselage to view the space above and below the craft.
